Facebook profile viewing?

[bty59150]

Can anyone help me out here? Is there any way to view someones profile on facebook? I've only just registered & I'm not 100% sure if the person I've seen IS the person I'm trying get in touch with.
To explain (I'm not a crazy stalker or pervert type person!!) I have 2 children (1 by the person I'm trying to contact & a 2nd by my current partner, who has accepted my 1st as his own). I KNOW deep down my morals know that I should let the father of my 1st child know that he DOES have a child. My 1st was the result of a 1 night stand after a works night out (both the pill & condoms failed!) and the person did ask if he was the father and I said NO (was in a relationship at the time which split up during the pregnancy).
I've constantly searched for him on the internet & only recently thought to try facebook (have looked on google, myspace, bebo etc, etc in the past).
Sorry to confuse anyone, but the jist is I need to be able to see the pic on profile & pic is to small to view on list.
